Abstract
A method of manufacturing an inverted metamorphic multijunction solar cell by providing a growth semiconductor substrate with a top surface having a doping in the range of 1×10to 1×10charge carriers/cm; depositing a window layer for a top (light facing) subcell subsequently to be formed directly on the top surface of the growth substrate; depositing a sequence of layers of semiconductor material forming a solar cell directly on the window layer; providing a surrogate substrate on the top surface of the sequence of layers of semiconductor material, and removing a portion of the semiconductor substrate so that only the high doped surface portion of the substrate, having a thickness in the range of 0.5 μm to 10 μm, remains.
